Way to have channel icons display in guide?

I've finally got my Roamio up and going and am loving it!! :)



I also just got a new tv which is HD, the channels of which are on complete different numbers than the ones I know. The guide doesn't display the channel logos/icons, only the letters (WSNLHD for example). I have no clue what that is. Is there a way to have the logos be displayed on the guide?
